/f/ h/l 1/ Attorneys Patented Mar. 29, 1938 UNITED STATES PATENT GFFICE 1 Claim.

Ihis invention relates to new and useful improvements for draining the edge portions of a roadway to prevent the settling of water at the edge portion of the road.

An important object of the invention provides a novel shoulder construction for roadways Whereby water will drain off of the edge portion of the road and .away from the road without settling at the edge portion of the road.

Other important objects and advantages of the invention will become apparent to the reader of the following specication.

In the drawings:

Figure 1 represents a fragmentary top plan View of the improved road construction.

Figure 2 represents a cross-sectional View on line 2 2 of Figure 1.

Figure 3 is .an enlarged fragmentary sectional view through one edge portion of the road.

Figure 4 is a perspective view of one of the lateral trough sections and fragmentary perspective view of one end of the longitudinal trough connected thereto.

Referring to the drawings, wherein like numerals designate like parts, it can be seen in Figure l that numeral 5 represents the usual rock road bed and numeral E the surface layer thereof.

At each edge portion of the roadway the shoulder is formed into individual sections 'l of any 3 predetermined length depending upon the level or inclination of the roadway (longitudinally speaking). These shoulder sections l are spaced from the edge portion of the roadway and their ends are spaced apart, as clearly shown in Figure 1. 35 Extending longitudinally between the shoulders 'I and the edge portion of the roadway is a trough 8. This trough is in sections and each section is disposed into the roadway end of a lateral trough 9. This lateral trough has the side walls a-a and 0 one end wall b. One of the side walls terminates short of the end Wall B and is provided with a laterally projecting retaining ange I0 which overlaps the outer wall of the trough 8 as shown in Figure 1 and serves to prevent spreading of said outer wall. The trough 8 communicates with the lateral troughs through the cut away portion of the short Wall. It can now be seen that the troughs 8 and 9 are iilled with crushed rock Il upto the level of the shoulder section l and top of the road surface B. It can be seen that ditches l2 are dug outwardly from the road on alignment with the lateral trough 9. Water comio ing off of the roadway surface and shoulders of the ro-ad will flow into these troughs and percolate through the crushed rock and subsequently oW out through the ditches I2 without leaving a settlement of water at the edge portions of the roadway, into which vehicle wheels can ride and in time create ruts which are hazardous to driving.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size, and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what claimed as new is:

In a roadway construction, longitudinally extending trough sections at the side of the road and in closely spaced relation therewith, a volume of crushed loose material disposed within the trough and laterally extending troughs at the b ends of said longitudinal trough sections, said lateral troughs comprising short and long parallel walls, said long Wall extending transversely of the longitudinal trough and spaced therefrom, said lateral troughs communicating with the longitudinal trough at the inner end of said short Wall and an angular extension at the inner end of the short wall and disposed in overlapping relation with respect to the outer wall of the longitudinal trough to prevent spreading thereof.
